of o distonce crsclose os 17 incheswithout
on occessory.  By odding on extension
odopter between the comero ond the lens,
pictures con be token from 17 inches to
10 inches. To toke picturesof stitl closer

between the extension odopter ond the
comero. The tubes ore suppliedin lengths
of  8,  l6  ond 32 mm. ond enoble the
photogropherio toke full frome pictures
of subiectsthe size of  postoge stomps,
ond even smoller .

  When using extension tubes the outo-
motic lens will not couple with the shutter
releose. In th is cose, it  is suggestedthot
two coble releoses be used, one on the
lens to close the diophrogm ond one on
the comero to  trip the shutter. This will
preserve the odvontogesof the outomotic
lens  for  close-up photogrophy.  The
shutter con be releosed by usingo coble
releose with q  Leico-type fitting ot  the
shutler  refeose b utfon  in  f ront ;  in th is
cose it will be more convenient if  the
lens is mounted with the red dot on the
lens lined up with the blue (insteod of
the red) dot on the qeXtensionodopter.
